Thin Film shader

Keyboard Shortcuts

The brand-new Thin Film shader allows you to create materials with a thin film effect giving the surface an iridescent quality. In this video, learn how to set up the shader for creating soap bubbles and enhanced reflective materials.

- [Instructor] Let's talk about the new thin film shader.…It has a pretty simple setup and allows you…to create a thin film effect on materials…giving the appearance of an iridescent surface.…If you're familiar with the spectral shader,…you'll know it has been around for a long time.…A few years ago I made this logo animation…using that spectral shader to get the iridescent colors…you see there.…I'm excited by the new thin film shader…because it kind of replaces this but maybe not entirely.…It's a very cool effect, as we'll see.…Now for the science.…

So we've got this sphere.…Let's just imagine that we have a thin film around it.…So what's gonna happen, the light hits the thin film,…comes through, and it's actually gonna be bounced…on both sides back and forth,…and you get this kind of interference happening.…So when both of the rays overlap,…the different paths will produce a change in color.…So now let's just take a look at the basic setup.…I've got some text here,…and a simple car paint shader that's in the content browser.…

What's new in CINEMA 4D R18? To start, there's updates to MoGraph, including a new object (Voronoi Fracture) and effector (Push Apart), as well as controls for clones, a Weightmap tag for effectors, and cache tags. In the modeling, animation, and rendering world, there's a new and improved Knife tool, a Thin Film shader for iridescent surfaces, new shader parameters, and viewport improvements like real-time reflections and tessellations. Andy Needham reviews all of these features and more, so you can get up and running with the latest version of CINEMA 4D as quickly as possible.
